Abstract

A method of displaying video surveillance system information is disclosed. Video clips associated with events are represented by event cards. The event cards include frames selected from the video clips associated with the events. Event cards include metadata, and can be annotated. Display of overlapping event cards causes a compressed event card to be displayed. Selection of a compressed event card dynamically expands the compressed event card to display a paneled event card.

Claims

1. A method of-displaying data comprising the steps of:

detecting an event in an video stream;

in response to detecting the event, selecting, from the video stream, an event video clip that is associated with the event and no other event;

without receiving any user input to indicate the frames to be selected, selecting a first frame from a first portion of the event video clip, selecting a second frame from a second portion of the event video clip;

in response to selecting the first and second frames, storing the first and second frames in an event card that is associated with the event;

wherein the event card is a visual indicator that represents the event video clip that corresponds to the occurrence of the event;

wherein the first portion is different from the second portion; and

causing the event card to be displayed;

wherein the method is performed by one or more computing devices.

2. The method of claim 1, further comprising:

receiving user input associated with the-event card; and

in response to the user input, playing the event video clip.

3. The method of claim 1, wherein the first portion of the event video clip is a beginning portion, and the second portion of the event video clip is an ending portion.

4. The method of claim 1, further comprising selecting a third frame from a third portion of the event video clip and storing the third frame in the event card, wherein the third portion is different from the first portion and the second portion.

5. The method of claim 1, further comprising generating a plurality of event cards for the event, wherein generating the plurality of event cards comprises storing a first particular frame in a first event card of the plurality of event cards and a second particular frame in a second event card of the plurality of event cards, wherein the first particular frame is different from the second particular frame.

6. The method of claim 1, further comprising storing a third frame associated with the event separately from the event card, wherein the first and second frames are different than the third frame.

7. The method of claim 6, further comprising, in response to selecting the event card, causing the third frame to be displayed.

8. The method of claim 1, wherein selecting the first frame comprises selecting at least one frame, from the event video clip, that satisfies one or more criteria, wherein the first frame depicts a motion relative to other frames from the event video clip, wherein characteristics of the motion satisfy said one or more criteria.

9. The method of claim 1, wherein selecting the first frame comprises:

selecting at least one frame from the event video clip that contains an image of a face;

determining a best view of the face in the selected at least one frame; and

storing the determined best view of the selected at least one frame in the event card.

10. The method of claim 1, further comprising storing metadata about the event in association with the event card, wherein causing the event card to be displayed additionally comprises causing the stored metadata to be displayed.

11. The method of claim 1, wherein detecting an event comprises receiving event notification from an external source.

12. The method of claim 1, wherein detecting an event comprises detecting motion in the video stream.

13. The method of claim 1, wherein detecting an event comprises detecting a face in the video stream.

14. The method of claim 1, further comprising receiving an annotation and storing the annotation in association with the event card.

15. The method of claim 1, further comprising providing one or more controls for sorting a plurality of event cards that correspond to a plurality of events based on at least one of the following criteria:

a selection of one or more cameras from a set of one or more cameras that captured the plurality of events, a specified time period, or the type of each event in the plurality of events, wherein the type includes at least one of the following types;

motion event, face event, and alert event.

16. The method of claim 1, further comprising providing one or more controls for searching across a plurality of events based on at least one of the following criteria:

a selection of one or more cameras from a plurality of cameras that captured the plurality of events, a specified time period, or the type of said each event, wherein the type includes at least one of the following types;

motion event, face event, and alert event.

17. The method of claim 1, further comprising providing one or more controls for scanning through a plurality of events, wherein the plurality of events were captured from a particular camera or a plurality of cameras.

18. The method of claim 17, wherein the one or more controls comprise at least one of the following:

a first button for causing an event that precedes in time a currently selected event from the plurality of events to be displayed or a second button for causing an event that follows in time the currently selected event to be displayed.

34. One or more non-transitory machine-readable media storing instructions which, when executed by one or more processors, cause the performance of the method recited in claim 1.

19. A method of displaying event card representations of events, comprising the steps of:

detecting a first event;

representing the first event in a timeline with a first event card;

wherein the first event card is a visual indicator that represents a first event video clip that corresponds to the occurrence of the first event;

detecting a second event after the first event;

wherein the second event card is a visual indicator that represents a second event video clip that corresponds to the occurrence of the second event;

determining whether the second event card would overlap the first event card in a display;

in response to determining that the second event card would overlap the first event card in the display, representing the first event in the timeline with a first compressed event card instead of the first event card; and

representing the second event in the timeline with a second event card;

wherein the method is performed by one or more computing devices.

20. The method of claim 19, wherein a selection of the first compressed event card causes the first compressed event card to expand to the first event card, temporarily overlapping the second event card.

21. The method of claim 20, wherein the selection of the expanded first event card causes at least one of the following:

displaying a segment of video associated with the first event and displaying metadata associated with the first event.

22. The method of claim 19, wherein first event card comprises an event card containing at least one frame from the first event video clip.

23. The method of claim 19, further comprising:

detecting a third event after the second event;

representing the third event in the timeline with a third event card; and

if the third event card would overlap the first and second event cards, then representing the first and second events in the timeline with a second compressed event card.

24. The method of claim 23, wherein the second compressed event card indicates the number of events that are represented by the second compressed event card.

25. The method of claim 23, wherein a selection of the second compressed event card causes a representation of the first event or a representation of the second event to be displayed.

26. The method of claim 25, wherein a selection of the representation of the first event causes the representation of the first event to expand temporarily to the first event card.

27. The method of claim 26, wherein a selection of the expanded first event card causes at least one of the following:

displaying a segment of video associated with the first event and displaying metadata associated with the first event.

35. One or more non-transitory machine-readable media storing instructions which, when executed by one or more processors, cause the performance of the method recited in claim 19.

28. A method of displaying event card representations of events in video data, comprising the steps of:

detecting a first event;

generating a first set of event cards for the first event, wherein the first set of event cards includes a multi-panel event card and a single-panel event card;

wherein each event card of the first set is a visual indicator that represents a first event video clip that corresponds to the occurrence of the first event;

representing the first event, in a timeline, using the multi-panel event card of the first set of event cards;

detecting a second event after the first event;

determining whether an event card of the second event would overlap the multi-panel event card of the first set;

if the event card of the second set would overlap the multi-panel event card of the first set, then dynamically changing how the first event is represented in the timeline by ceasing to represent the first event with the multi-panel event card and representing the first event with the single-panel event card of the first set of event cards;

wherein the method is performed by one or more computing devices.

29. The method of claim 28, wherein generating a first set of event cards for the first event comprises:

selecting at least one frame from a first event video clip associated with the first event; and

generating at least one event card that comprises the at least one selected frame.

36. One or more non-transitory machine-readable media storing instructions which, when executed by one or more processors, cause the performance of the method recited in claim 28.

30. The method of claim 30, wherein:

the event card of the second event is a multi-panel event card of a second set of event cards; and

the method further comprising if the multi-panel event card of the second set would overlap the single-panel event card of the first set, then dynamically representing the first event in the timeline with a compressed event card associated with the first set of event cards.
